chore: fix build for .NET 10 preview4

[filzrev]

This PR fix build error when using .NET 10 preview4 (It's occurred only when using Visual Studio Preview)

It's caused because .NET 10 preview4 or later contains build-in InlineArray16<T> implementation.
So It need to exclude ZLinq's InlineArray16<T> implementation for .NET10 build.

---

Additionally .NET 10 preview 4 add following methods for FrozenCollection.

• FrozenDictionary.Create
• FrozenSet.Create

As far as I've confirmed.
These methods are simple wrapper and no performance benefits to use these methods.

Example Code

    public static FrozenSet<TSource> ToFrozenSet<TEnumerator, TSource>(this ValueEnumerable<TEnumerator, TSource> source, IEqualityComparer<TSource>? comparer = null)
       where TEnumerator : struct, IValueEnumerator<TSource>
#if NET9_0_OR_GREATER
        , allows ref struct
#endif
    {
#if NET10_0_OR_GREATER
        using var e = source.Enumerator;
        if (e.TryGetSpan(out var span))
            return FrozenSet.Create(comparer, span); // Almost same performance to `source.ToHashSet().ToFrozenSet()`

        // When using ToArrayPool. it run slower 10-20%
        using var pooledArray = source.ToArrayPool();
        span = pooledArray.Span;
        return FrozenSet.Create(comparer, span);
#else
        return source.ToHashSet(comparer).ToFrozenSet(comparer);
#endif
    }

Thank you!
I see, I completely forgot about the conflicts.
I understand about the Frozen***.Create too.
It seems fine to leave it as is for now, but I'll keep an eye on it.
